Hello,
@smudge75
Its great that you are doing this with support of your doctor. Are you using meal replacement products or real food?
The one main thing I wish I had been told at the start (apart from the fact that in addition to the meal replacement product you can have vegetables) was to have some oil as this can prevent formation of gall stones.
Keep posting about progress, and start forming a plan of how and what your follow on eating plan will be. That is often forgotten about.
